Default Re: outdoor poly

I don't know much about clear water based exterior finishes. I do know nothing clear lasts very long when exposed to the UV rays of the sun. However, WB finishes are more flexible than oil based stuff so there should be less checking of the finish so less moisture will seep into the wood.

Of the oil based clear finishes Spar varnishes have a higher ratio of oil to resin and are the most flexible.

Dry rot is the result of a fungus growing in moist wood. Termites don't live in the wood but they do eat it. Bora Care is supposed to prevent both. I should have said it's a insecticide and an fungicide.
